We employ the singular sources method introduced in [4] to solve an inverse transmission scattering problem for the Helmholtz equation 4u þ j 2 u ¼ 0 in R m n D or D, respectively, where the total field u satisfies the transmission conditions u þ ¼ u À and @uþ @m ¼ b @uÀ @m on the boundary of some domain D with some constant b. The main idea of the singular… (More)

GOAL, SCOPE, BACKGROUND: Shallow lakes display a number of features that set them apart from the more frequently studied deeper systems. The majority of lakes in Northern Greece are small to moderate in size with a relatively low depth and are considered as sites of high value of the wetland habitat. However, the water quality of these lakes has… (More)

Metaplastic carcinomas of the breast are uncommon lesions and account for < 5% of all breast malignancies. A type of metaplastic carcinoma is carcinosarcoma, an even more rare lesion. We present a case of carcinosarcoma in association with Von Recklinghausen's disease in a 60-year-old woman. Von Recklinghausen's disease is an autosomal dominant disorder… (More)
